Abstract: Bearing systems for high speed rotating shafts, such as turbocharger shafts, include a first ball bearing in one end of an elongated cylinder capable of carrying axial thrust in both directions and a second ball bearing in the opposite end of the elongated cylinder with its outer race slideably mounted in the cylinder against the biasing force of a preload spring. The second ball bearing is free to move axially with the shaft upon axial expansion of the shaft when exposed to high temperature. The inner races of the ball bearings are clamped to and rotate with the shaft as part of the rotating assembly.

Abstract: The performance of a computer system displaying polygonal forms is improved by method and apparatus including a cache storage device and related control hardware operating in conjunction with a pipeline graphics display system to reduce or eliminate the redundant matrix transformation of shared vertex data, thereby reducing the processing time required to generate the graphics images displayed for out-the-window simulation.

Abstract: A sill cover article for automobiles and other vehicles which has a first, relatively rigid sill cover portion and a second, relatively flexible lower door sealing portion that is manufactured as a single component and can be attached to a vehicle in a single mounting operation. The sill cover article is preferably manufactured of two materials of different durometer which are coextruded to form a single component. The sill cover article or a portion thereof may be provided with various coatings and/or additives to provide the article with desired properties. For example, the lower door sealing portion may be provided with an ice-release agent to prevent ice from forming on a surface thereof. The sill cover article of the present invention provides a reduction in assembly time, inventory requirements and overall manufacturing costs of a vehicle.

Abstract: A primed fuel is manufactured by the application of particles of a combustible primer, such as wax, to a fuel, such as charred wood. In the method and apparatus of this manufacture, fuel is transported through a deposition zone within the apparatus. A liquid supply of combustible primer is provided and formed into droplets and deposited in droplet form onto the fuel, preferably by electrostatic deposition. The primer tends to be preferentially deposited at the more readily ignitable edge of the fuel.
